We are talking about voting behavior, not racial backlash, and the two are not automatically connected. From the 1930s through the 1980s, Democrats largely dominated national politics. The Republican Party did not pose a serious electoral threat until the economic downturn of the late 1970s, which helped bring Ronald Reagan into office. This shows that you can have racial backlash without a corresponding voting backlash. When the economy is stable, racial resentment does not necessarily translate into higher turnout. When the economy is unstable, however, voting patterns shift dramatically. Economic anxiety played a major role in the rise of the Reagan administration, the political wave that reshaped the Obama presidency in 2010, and the conditions that helped Donald Trump win support. After World War Two and during the New Deal era, even as desegregation created intense racial resentment among many white Americans, they did not mobilize in large numbers at the polls because the economy was strong. Their racial anger existed, but it did not convert into political action.The pattern is consistent. The most volatile political moments in the United States tend to occur when white voters, especially those in economically vulnerable positions, feel financially insecure. When they struggle, the country enters periods of political upheaval, and the consequences ripple outward. One of the most dangerous thing in America is a poor white man which we're seeing today.
